POWER-DRIVEN BRUSH FOR MEAT BLOC-KS.

Application filed June 14, 192?. fierial No. 198,843.

My invention relates to power driven rotary brushes.

In accordance with my invention, 1 provide a device which is designed to clean meat blocks. The device embodies a casing or body portion upon which is mounted a motor. A rotary brush is arranged Within the casing or body portion to engage with the meat block and is driven by the motor. Handles are arranged. at the ends of the body portion and the motor is preferably arranged centrally of the housing or body portion, and the device is, therefore, substantially balanced, for ease and convenience of manipulation. Means are also provided whereby the brush may be vertically adjusted with respect to the housing.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a plan view of a brushing device embodying my invention,

Figure 2 is a side elevation of the same,

Figure 3 is a longitudinal section taken on line 3-3 of Figure 1, parts in elevation,

Figure 4- is an elevation of one end of they device,

Figure 5 is a transverse section taken on line 5 of Figure 2,

Figure 6 is a similar view taken on line 6-6 of Figure 2, and,

Figure 7 is a detailed section through one of the brush bearings.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral. 10 designates a housing; or casing as a whole, embodying a top 11, ends 12. and a rear side 13, thus leaving the forward side and bottom of the housing open, as shown. The numeral 14. designates horizontally arranged handles, carried by U- shaped bases 15. which are rigidly attached to the ends 12 adjacent to the extremities of the same and adjacent to the top 11, while the handles 14 have their central longitudinal axes in alinementwith the central longitudinal axis of the top 1.1. This provides the device with a low center of gravity, and a perfectbalance of parts, during manipulation. 7 Y

The numeral 17 designates a rotary brush, preferably embodying wire bristles. This re tary brush is rigidly mounted upon a brush shaft This shaft has its ends journaled in 19, positioned within segmental in clined slots 20, formed in the ends 12. The bearings 19 are provided upon their inner ends with flanges 21, while their outer ends are screw-threaded for receiving lock nuts 22. The bearings 19 may, therefore, be ad justed longitudinally within the segmental slots 20, and clamped to the ends 12 in selected adjusted positions, thereby regulating the elevation of the shaft 18 with respect to the housing 10.

Mounted upon the top 11 of the housing 10, and centrally thereof, is a motor 23, rigidly secured thereto by any suitable means. This motor has its armature shaft 24- extending longitudinally of the housing 10, and coin ciding with the central longitudinal axis of the same. The armature shaft 24 is provided with a gear 25, rigidly secured thereto, and this ear drives a gear 26, rigidly mounted upon a longitudinal connecting shaft 27. The shaft 27 is journaled within a longitudinal housing 28, mounted upon the top 11, and rigidly attached thereto. The shaft 27 also coincides with the central longitudinal axis of the top 11. The gears 25 and 26 are preferably covered by a housing 28.

Formed upon the outer ends of the shaft housing 28 is a gear housing 29, receiving a gear 30, rigidly attached to the outer end of the shaft 27. This gear 30 is in permanent mesh with a gear 31, rigidly mounted upon one end of the shaft 18. The shaft 27 is at the central longitudinal axis of the top 11, as explained, and the segmental slot 20 is concentric with the shaft 27, inclined, and has its lower end in vertical alinement with the shaft 27. Hence when the brush sh aft 18 is shifted to the inner ends of the slots 20. the brush is at the lowermost position, and may be raised by shifting the shaft 18 toward the outer ends of the curvedslots 20.

In operation, the motor drives in a direction to turn the brush 17 counterclockwise. Figure 6. so that the lower portion of the brush is traveling forwardly. The rotating brush acting upon. the surface of the block will, therefore, sweep the'meat or the like forwardly through theopen side of the hous ing' 10, as the device is being advanced, by the operator engaging the handles 14. The arrangernent is such that the parts of the device are well balanced, and the device may be manipulated with great ease.

It is to-be understood that the form of i'ny invention, herewith shown described, is

' to be takenas a preferred example ofthe same, and that various changes in the shape, size and arrangement of parts may be resorted to Without-departing from the spirit ofmy invention, or the scope of the 'suhjoined claim.

Having thus described myim'ention, I'

ulai'm v o o A meat block cleaning device, Comprising a casing havinga top and'depending ends, a.

IIlOt'OIHlQUIltGCl centrally upon the top of the casing, a drive shaft driven'by the motor and arranged'atone endrof the motor and extendinglongitudinally of the casing and terminating adjaoent'to one end thereof, a rotary 1 5 brush arranged within the, casing and extending longitudinally thereof a horizontal handlehav-ing au-shaped'base attached to that end of the oasing adjacent to the outer end of the drive shaft, a gear housing mounte'd'withintheU=shaped base, a gear connect-ed with the; drive shaft and arranged Within the gear lious1ng,- driving conneotlng means between said gear, and the rotary brush,-and a seoond horizontal handle attached to theoppositeend of said casing.
